Ko-hen 72 Tooth Z-Series Ratchet

Ko-ken ratchets are known for their very low backlash, small head sizes, and high torque ranges.  We designed the new 72 tooth ratchet without compromising on our traditional strengths.  The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet.  The legacy 36 tooth ratchets move 10°/click. The new 72 tooth ratchets move 5°/click.
